Referring to the drawings and to the preferred form 'of my invention asillustrated j therein, I have shown a socket preferably -v tachingyscrewa securedthereto in substantially the same manner as illustratedand described vin the (izo-pendingapplication' of Andrew G. Anderson,Serial'No. 708,724, filed' 'April 24th, 1924. The casing presents aiange 3 at Athe outer end thereof for engage'- ment' with the face ofthe support 4 to i which the socket'is attached, and the front 4 der- 5,the purposes lof whichare more fully hereinafter described. 'The' socketalso includes a stud-receiving part 6 vpresenting af studreceivingaperture and a. locking member 7 normally urged into aperture-closingpositionby a spring 8 which lalso urges the stud-receiving part forwarduntil. it seats against the front-facerof the casing."The stud-receivingpart is preferably provided with a substantially long tubular partclose.- ly slidably fitting the inside of the casing.

The preferred form of stud for use with the Asocket herein described issecured to a frontl elevation ,of the 'pre "f'shows ,thestud movedaxially 'intothe socket g1-nd* the lockingl member in unlocked posi-j'/f of the so-called flush type. v The socket-,com-` prises a body partor casi'ngl 1 having an at-l ace of the 4casing'presents an annularshoul-y iexible carryingfabric'lO, and presents a vsocket-engagingcontractible and expansible head lland a latch 12 pivot-ed thereupon.

` Theattaching means, the stud and the oprasant eration thereof aresubstantially illustrated and 'Umore fully described in my co-pendingapplication filed herewith, Serial No. 719,-

924. The only substantial variation between the stud herein illustratedand, the stud illustrated in the above-mentioned application is 'in theneck: In this instance, the neck is of the usual construction, havinglittle orr no lost motion between .it and the stud-receiving part whenthe stud and socket are lockedftogether.

Engagementoi Vthe stud and socket may lsocket thereby engaging the vheadoit'v the stud with the stud-receiving part adjacent ybe effected bypressingthe stud toward the the' stud-receiving aperture. As furthervpressure is-applied'to enter the head in the aperture, thestud-receiving. part moves :axially inward against the pressure of theVspring`8 yandfrelative to the socket until the end lof the tubular 'partseats against the head of the attaching screw. Still further ,pressureurges the head to contract and enter the stud-receiving aperture at thesame Vtime urging the locking member out of the aperture against thepressure of the spring 8. A'lfhus the-head enters the aperture and againexpands, the neck thereof engaging the peripheralwall surrounding thestudreceiving aperture. Pressure is now released from the stud and thespring 8 thenurges the. stud-receiving part (Sinto its normal`positionagain and at the same t-ime'gthe locking member -7 is free tobe urged bythe v spring8 .into 'engagement with the reve-rselvbentportions of the stud, asbest illustiated in Fig. 2, therebylockingthe stud.

and socket again-st separation by a pull at any side'thereof. The Studisalso locked againstseparation by an upward pull becausethe end of theVlatch that engages the face of the socket contacts with ,the annularshoulderf, which provides a very effective stop `thereby preventing aresolution of.

forces `from tipping the stud out of engagement with the stud-receivingpart. l

Separation of the stud from the socket is eliected by first pressing thestudv toward the best shown in Fig. 4.

`While I have shown and described a preferred form of one lembodiment ofmy 1nvention, it will be understood that changes involving omission,substitution, alteration and reversal of parts, and even changes in themode of-operation, may be made'with- Aout departing from the scope of myinvention, which is best dened in t-he following claims.

I claim- 1. A stud and 'socket fastener comprising,

in combination, a socket including fa casing, a vstud-receiving part4movable relative to said casing, a cooperating stud for engagement withsaid stud-receiving part, locking means forming part of the fastenerassembly for locking said stud with the socket and unlocking meansvseparate from lsaid locking means and carri'edby'said stud fordisplacing' said locking means to permit separation of the fastener whensaid stud and stud-receiving part are moved relative to s'aid casing. YY

2. A stud and socket fastener lcomprising, in combination, a socketincluding a casing, a stud-receiving part movable relative to saidcasing, a cooperating stud for engagement with said stud-receiving part,locking means forming part of the fastener assembly fo'r locking saidstud with the socket, a latch operable to displace said locking meansand means adjacent said latchr to prevent tipping of said stud relativeto said socket when lateral strain is exerted in the direction of saidmeans.

3. A stud and socket fastener comprising, in combination, a socketincluding a casing, a stud-receiving part movable relative to saidcasing, a vcooperating stud for engagement with said stud-receivingpart, locking means forming part of the fastener assembly forlocking'said stud with the socket, a latch operable to 'displace saidlocking means and a shoulder located upon said socket l`and engageableby said latch when a lateral strain is exerted upon 4said stud fromabove lsaid latch.

4. A stud and socket fastener comprising, in combination, a socketincluding a casing, a stud-receiving part and a spring-pressed lockingmember normally urging said studreceivin'g part `into its forwardposition, a cooperating stud having a head for engagement with saidstud-receiving part and adapted whenengaged therewith to receive saidlocking member to prevent separation of said stud from saidstud-receiving part and a latch pivoted upon said head and operable byaxial movement ofsaid stud and stud=receiving part relative to said'casingv thereby to displace said locking member from said head andpermit separation of said fastener.

5. A studand socket fastener comprising, in combination, a socketincluding a casing, 'a stud-receiving part axially movable in saidcasing and presenting a stnd-receivingaperture surrounded by a wallofxed Vdimensions, and means forming part ofthe socket for limiting themovement of said ystud-receiving part, a stud having aj contractible andexpansible head engageable W-ith said stud-receivingI part aftermovement thereof to its inner limited position and springpressed lockingmeans within 'said stud-re'- ceiving part for moving said stud andstudreceiving part tok the forward limit and for locking said partstogether. Y Y

6. A stud and socket fastener comprising, in combination, a socketincluding a easing, a stud-receiving part axially mov-able in saidcasing and means for limiting the movement thereof, a stud-having acontractible and exp'ansible head e'ngageable with said stud-receivingpart after movement thereof to its inner ,limited position, separatespringpressed locking means forming part ofthe socket for -moving saidstud and "stud-receiving part to the forward limit and locking saidparts together, and an latch forming part of the fastener assembly 'andoperable by inward-movement of said stud-receiving part relative to saidcasing to shift said loc-king means and permit separation of said studand socketv Y 7.V A stud and socket fastener compri-sing, incombination, a socket including aV shiftable stud-'receiving part, astud for 'engagement therewith, resiliently pressed locking meanscarried by said socket for'locking said stud with said stud-receivingpart andV unlocking means pivotally mounted upon the `stud and operablerelative to sai'd studr'eceiving part, without movement between the studand stud-receiving part, to move said locking means into unlockingposition relative to said stud.-

8. .A socket for a separable fastener inclu-ding a casing, an axiallymovable springpressed stud-receiving part shiftable relative to saidcasing, said part presenting a stud-receiving aperture, means forlimiting the shiftingl of said part in said casing, an axially shiftablespring-pressed closure plate forming part `of the socket assembly `andnormally closing, said aperture to exclude dust and dirt from saidsocket, and locking means carried by said plate and presented at saidaperture for engagement with and a spring normally urging saidstud-rethe stud. ceiving part and said locking member into 9, A socketfor a separable fastener innormal position said stud-receiving part and10 Vcluding a casing, means for attaching said said spring beingassembled with said casing. 5 casing to a support, an axially movablenon- In testimony whereof, I have signed my resilient stud-receivingpart, a locking memname to this specification.
